 * $Log: kjavaappletserver.h,v $
 * Revision 1.8  2000/09/27 11:46:32  sschiman
 * * I've added implementations for the showDocument and showStatus calls to kjas
 * for java applets that want to change the location of a frame. This should fix
 * java menus. (okayed by Lars and mhk)
 *
 * Revision 1.7  2000/06/06 22:53:36  gehrmab
 * Beauty and wellness for the API documentation
 *
 * Revision 1.6  2000/03/21 03:44:44  rogozin
 *
 * New Java support has been merged.
 *
 * Revision 1.5  2000/01/27 23:41:56  rogozin
 * All applet parameters are passed to KJAS now
 * Next step - make use of them.
 *
 * Revision 1.4  1999/12/14 19:56:59  rich
 * Many fixes, see changelog
 *
 * Revision 1.3  1999/11/12 01:22:34  rich
 * Now trys adding a / to the code base if the class loader could not find the applet class file. Fixed applet start/stop
 *
 * Revision 1.2  1999/10/09 18:10:10  rich
 * Const QString fixes
 *
 * Revision 1.1.1.1  1999/07/22 17:28:07  rich
 * This is a current snapshot of my work on adding Java support
 * to KDE. Applets now work!
